This includes use of full backstick, if demanded.
Note: 1. If engaged, the autopilot will disengage, when α greater than α prot.
2. If FD bars are unavailable, use an initial pitch attitude up to 12.5 ° with full
backstick, if necessary. If needed, to minimize the loss of height, increase this
pitch attitude.
DO NOT CHANGE CONFIGURATION (SLATS/FLAPS, GEAR) UNTIL OUT OF SHEAR.
CLOSELY MONITOR FLIGHT PATH AND SPEED.
RECOVER SMOOTHLY TO NORMAL CLIMB OUT OF SHEAR.

WINDSHEAR
Applicable to: ,
A red flag “WINDSHEAR” message is displayed on each PFD, associated with an aural
“WINDSHEAR” message, repeated three times.
If windshear is detected, either by the system or by pilot observation, apply the following recovery
technique:
At takeoff:
If before V1:
The takeoff should only be rejected if significant airspeed variations occur below indicated
V1, and the pilot decides that there is sufficient runway remaining to stop the airplane.
If after V1:
THR LEVERS...............................................................................................................TOGA
REACHING VR........................................................................................................ROTATE
SRS ORDERS........................................................................................................ FOLLOW
Airborne - initial climb or landing:
THR LEVERS AT TOGA.............................................................................. SET OR CONFIRM
AP (if engaged)...................................................................................................................KEEP
SRS ORDERS...............................................................................................................FOLLOW
This includes use of full backstick, if demanded.
Note: 1. Autopilot will disengage, when α greater than α prot.
2. If FD bars are unavailable, use an initial pitch attitude up to 17.5 ° with full
backstick, if necessary. If needed, to minimize the loss of height, increase this
pitch attitude.
DO NOT CHANGE CONFIGURATION (SLATS/FLAPS, GEAR) UNTIL OUT OF SHEAR.
CLOSELY MONITOR FLIGHT PATH AND SPEED.
RECOVER SMOOTHLY TO NORMAL CLIMB OUT OF SHEAR.

WINDSHEAR AHEAD
Applicable to: ALL
The “W/S AHEAD” message is displayed on each PFD. The color of the message depends on the
severity and location of the windshear.
Note: When a predictive windshear alert (“WINDSHEAR AHEAD”) is triggered, if the flight crew
makes a positive verification that no hazard exists, then the alert may be disregarded, as
long as:
There are no other signs of possible ‐ windshear conditions, and
‐ The reactive windshear system is operational.
Known cases of spurious predictive windshear alerts have been reported at some airports,
during either takeoff or landing, due to the specific obstacle environment.
However, always rely on any reactive windshear (“WINDSHEAR”).
W/S AHEAD RED
Takeoff:
Associated with a synthetic aural voice: “WINDSHEAR AHEAD, WINDSHEAR AHEAD”.
Before takeoff:
Delay takeoff, or select the most favorable runway.
During takeoff run:
Reject takeoff.
Note: The predictive windshear alerts are inhibited above 100 kt, until 50 ft.
When airborne:
THR LEVERS...........................................................................................................TOGA
As usual, the slat/flap configuration can be changed, provided the windshear is not
entered.
SRS ORDERS.................................................................................................... FOLLOW
Note: If engaged, the autopilot disengages when α is greater than α prot.
Landing:
Associated with a synthetic aural voice: “GO AROUND, WINDSHEAR AHEAD”.
GO AROUND..........................................................................................................PERFORM
This includes use of full backstick, if required.
